A fresh effort is under way to refloat a giant container ship blocking Egypt’s Suez Canal.
Canal authorities say 14 tugboats are trying to take advantage of Saturday’s high tide and more will arrive subsequently if the latest attempt fails.
The Ever Given became wedged in the canal – one of the world’s busiest trade channels – on Tuesday.
More than 300 ships are stuck on either side of the blockage. Some have had to reroute around Africa.
By late Friday, dredgers had moved about 20,000 tonnes of sand from around the Ever Given’s bow, which was stuck deep into the canal’s bank.
The chairman of the Suez Canal Authority (SCA), Osama Rabie, told a news conference on Saturday that 9,000 tonnes of ballast water – which is stored in tanks to stabilise the ship – had been removed to help lighten the vessel.
He said the stern had begun to move on Friday night, and that the rudder and propeller had started working again. Strong tides and winds had made freeing the ship more difficult, he added.
Mr Rabie could not say how soon the ship might be refloated but said the SCA would “work around the clock” to get other ships through once the Ever Given was free.
Initial reports said the 400m-long (1,300ft), 200,000-tonne vessel ran aground in high winds and a sandstorm that affected visibility.
However, Mr Rabie said weather conditions were “not the main reasons” for the ship’s grounding.
“There may have been technical or human errors,” he told reporters, without giving details. “All of these factors will become apparent in the investigation.”
